San Diego County, San Diego Rat Control Situation:
Hi David, Is a UV blacklight still useful, exterior-wise, if it rains after the rodents leave their urine stains? I am in the process of performing exterior maintenance to better exclude my roof rats. 1) I have a 25 year old cedar shake roof in San Diego California with openings under each shake along the rake edge of the roof at the gable ends of my house. There's no drip edge, i.e. under the shakes I have roofing paper (now somewhat curled) that runs more or less up to and rests right atop the fascia board. Because I have skip sheathing, and since the cross section of a shake is a wedge that is up to one inch at the upper, thick end, this appears to create many huge entry points along the rake edges even though the sheathing is rabbeted into the fascia board. As a result, I'm thinking of getting a UV blacklight to use outside the house to sleuth for urine stains along the upper edge of the gable end shakes and fascia boards. My question is, how easily does the winter rain wash away the urine, rendering this a pointless exercise? 2) I noticed a new product called "rat-out gel" and was thinking of applying it along the rake edges mentioned above. Or, maybe I should just buy many rolls of X-Clude and use that instead. Or maybe both. Any comment? Thanks very much for your website, Doug
My response: First off, I do not have experience using UV lights to detect rat urine. But I do suspect that rain will severely limit the effectiveness of this approach. I have never heard of Rat-Out Gel or XClude, but I typically stick to physical barriers rather than repellent type devices. If your roof makes this impossible, you might have a tough time keeping the rats out.
San Diego Rat Control Tip of The Week
Tips To Find And Remove A Dead Rat
Rats sneak into hard-to-reach areas. They sometimes end up dying of hunger, trapped by the walls or the elements of the roof. A foul odor can fill the room after a few days, causing discomfort to occupants and threatening their health. Here are some tips for dealing with this case.
Identify And Dislodge The Remains Of The Rodent.
The smell is the first tool to locate the carcass of a dead rat. Therefore, it is necessary to walk in the concerned area, keeping your nose near the walls, pipes, or the ceiling, for example. The carcass is located where the odor emanates the most. Equipped with gloves and tools like a saw, screwdriver, flashlight, etc., you have to create an opening to remove the carcass. It is important to disinfect the area where the dead rat was found to avoid more serious illnesses.
What To Do With The Carcass?
The law prohibits dumping any animal carcass in waterways, garbage cans, public roads, or any other place. As soon as the dead rat is dislodged, it should be placed in a sealed plastic bag. Only then will it be possible to put it in the trash. However, it is best to burn the remains if possible. Burial is also possible, but there is a minimum of depth to be respected.
